• High-Performance Engineering: Features a 66.40mm bore for precise fitment and enhanced engine operation.
• Durable Material: Constructed from high-silicon content Hypereutectic cast aluminum, offering reduced heat expansion, tighter clearances, increased hardness, and a longer lifespan.
• Reduced Friction & Wear: MOS2 (Teflon/Molybdenum) coated skirts significantly reduce friction and heat, promoting superior performance and longevity.
• Optimized Crown Design: Machined, smooth piston crowns minimize carbon buildup, contributing to increased horsepower and improved fuel economy.
• Enhanced Durability: Hard anodized crowns are 75% stronger than non-anodized versions, providing minimal expansion and reducing the risk of cold seizures.
• Complete Assembly: Piston assemblies include ring(s), wrist pin, and circlips for a straightforward installation.
• Oversize Options: Available in fractional oversize pistons (-B and -C) to extend cylinder life by renewing original clearance, potentially avoiding costly sleeve installations.
